Definitions
- the present invention relates to a light emitting module including a light source such as a light emitting element, an illumination device that employs the light emitting module, a display device that includes the illumination device, and a television receiver that includes the display device.
- a light emitting module including a light source such as a light emitting element, an illumination device that employs the light emitting module, a display device that includes the illumination device, and a television receiver that includes the display device.
- a backlight unit for supplying light is usually mounted on the liquid crystal display panel.
- the light source is an LED (Light Emitting Diode).
- a lens 110 for diffusing light from an LED mounted on a mounting substrate 120 is attached (a module including the LED, the lens 110, and the mounting substrate 120 is a light emitting module). mj).
- This image includes a rectangular area (dotted line area) at the center, four corner areas (dashed line area), and other areas. Therefore, the area surrounded by the dotted line is ar1, the area surrounded by the alternate long and short dash line is ar3, and the other areas are ar2. If the illuminance [lumen] of these areas ar1, ar2, ar3 is ln1, ln2, ln3, the relationship between them is lm1> lm2> lm3.
- the planar light generated by the LED module mj includes light amount unevenness.
- a plurality of types of lenses 110 having different directivities of transmitted light such as a lens corresponding to the area ar1, a lens capable of guiding light to the area ar2, and a lens capable of guiding light to the area ar3, are mounted on the mounting substrate 120. It is good to be done. This is because with such an LED module mj, the directing direction of transmitted light can be set so as to face, for example, the areas ar2 and ar3 that tend to be dark portions, and the dark portions can be lost.
- the manufacturing cost increases due to the increase in the types of lenses 110.
- the mounting position is determined on the mounting substrate 120 for each type of lens 110, it takes time to identify the lens 110, and the manufacturing time of the LED module mj must be long (in essence, the lens 110 has a long time). Positioning is troublesome.
- the present invention has been made to solve the above problems. And the objective is to provide the light emitting module etc. which aimed at the reduction of the manufacturing burden, suppressing the increase in the kind of lens.
- the light emitting module includes a light emitting element, a mounting substrate on which the light emitting element is mounted, and a lens that receives light from the light emitting element and emits the light. And in this light emitting module, a lens may emit in the directivity direction which is the direction which deflected a part of light. In such a case, in the light emitting module, one of the first restricting portion and the second restricting portion that are engaged with each other is formed on the mounting substrate, and the other is formed on the lens. The directing direction of the lens is restricted to a specific direction by the mutual relationship of the streets.
- the direction of the lens (for example, the direction of the lens) is restricted by the first restricting portion and the second restricting portion that have only one way of engagement. Becomes easier. That is, the manufacture of the light emitting module is simplified.
- the illuminance distribution of light from the light emitting module (and thus the luminance) can be obtained without changing the shape of the lens surface of the lens. Distribution) varies. Therefore, for example, even with one type of lens, the illuminance distribution of light from the light emitting module can be changed variously. That is, a light emitting module that can be easily manufactured while reducing the manufacturing cost by reducing the cost of the lens is realized.
- first restricting portion and the second restricting portion to be engaged have a shape that can be fitted. This is because the structure is simple if it is such a first restricting portion and a second restricting portion.
- another member attached to the mounting substrate may be engaged with the other restricting portion and serve as one restricting portion. This is because using a separate member may reduce the cost of the light emitting module as compared to forming the restricting portion on the mounting substrate.
- first restricting portions and the number of second restricting portions may be the same and singular, or the same and plural. If it becomes like this, the freedom degree of design of a light emitting module will increase according to the cost concerning both control parts.
- the type of one restricting portion formed on the lens is different for each different type of lens, and the type of the other restricting portion is also different depending on the different type. It is desirable to make it different.
- the type of one restricting portion formed on all the lenses is single, and the type of the other restricting portion is also simple according to the single type. It is desirable to be one.
- a lighting device including the light emitting module as described above is also the present invention
- a display device including such a lighting device and a display panel (for example, a liquid crystal display panel) that receives light from the lighting device is also present.
- a television receiver is an example of a device on which such a display device is mounted).
- the light emitting module of the present invention since the direction of the lens is determined in advance by the first restricting portion and the second restricting portion, the light from the light emitting module can be transmitted without changing the shape of the lens surface in the lens.
- the illuminance distribution can be changed variously, and the manufacturing is simple. Therefore, the cost required for the lens can be reduced, and the cost of the light emitting module can also be reduced.

- the illuminance of the planar light formed by the plurality of LEDs 31 by covering the LED 31 with one kind of lens 10 The distribution can be changed variously (for example, the illuminance near the center of the planar light can be increased or the illuminance near the periphery of the planar light can be increased). This is because light is diffused through the lens 10 and has directivity, and the directivity direction is arbitrarily set.
- the manufacturing cost of the lens 10 can be suppressed, and as a result, the cost of the LED module MJ, the backlight unit 49, and the liquid crystal display device 69 can be reduced.

Therefore, the cost of the LED module MJ, the backlight unit 49, and the liquid crystal display device 69 can be reduced.
- the trapezoidal shape (cross-sectional shape intersecting in the axial direction) around the shaft portion 12D of the pin 11D is not point-symmetric and is not line-symmetrical, and the trapezoid of the opening 21D is also point-symmetrical according to the trapezoidal shape. Neither is it line symmetric (note that this trapezoid has an angle of three of the four corners of 90 °).
