Description

A kind of LED spotlight with reflective cup

technical field

The utility model relates to the technical field of lighting fixtures, in particular to an LED spotlight with a reflective cup.

Background technique

Traditional LED spotlights usually use LEDs to directly emit light towards the object, and add a lens to determine the light angle, which cannot be adjusted arbitrarily. Since LED is a point light source, it is easy to cause glare and glare when people look directly at it.

Utility model content

The technical problem to be solved by the utility model is that the improved LED point light source is likely to cause glare and glare when people look directly at it. The light emitted by the LED is reflected, focused and then refracted to the object, effectively improving the traditional LED light source when people look directly at it. Sometimes glare, glare and the shortcomings of not being able to adjust the lighting angle arbitrarily.

The technical solution adopted by the utility model to solve the technical problem is: an LED spotlight with a reflective cup, including LED, heat sink lamp body and circuit board, the LED spotlight also includes a metal rod and a reflective cup, metal The rod is set on the heat sink lamp body, or a metal rod is derived from the heat sink lamp body, more than one LED is welded on the circuit board, the circuit board is fixed on the metal rod, and the LED is directly fixed on the metal rod; reflective The cup is set at the bottom of the metal rod, and the LED protrudes from the circuit board or metal rod in the reflective cup; when powered, the LED light can be concentrated through the reflective cup and projected to the target; the heat generated by the LED can be conducted to the heat sink by the metal rod Sheet lamp body, and then the heat is dissipated by the heat sink lamp body to achieve the purpose of lighting.

In the above technical solution, the LED spotlight further includes a cup cover, the reflective cup is arranged in the cup cover, and the cup cover and the heat sink lamp body are assembled together.

There are screw teeth on the bottom of the reflector or inside the cup cover, and screw teeth are also provided on the relative position of the heat sink lamp body. The reflector cup and the heat sink lamp body or the cup cover and the heat sink lamp body are assembled together in a threaded connection. When the reflector cup or cup cover is rotated, the focal length of the LED on the reflector cup can be changed to achieve the purpose of arbitrarily adjusting the light emitting angle.

The inner diameter of the bottom of the reflector or the inner diameter of the cup cover is tightly matched with the outer diameter of the heat sink lamp body at the opposite position to form a sleeve. When the reflector or cup cover is pushed and pulled, the focal length of the LED to the reflector can be changed to achieve arbitrary adjustment. The purpose of the light angle.

The beneficial effect of the utility model is: the LED spotlight with the reflective cup of the above structure, in order to improve the glare and glare shortcomings of the traditional LED when looking directly at it, the LED light is projected to the target through the reflective cup, and the heat generated by the LED can be reduced. The heat is transmitted to the heat sink lamp body through the metal rod, and then the heat is dissipated by the heat sink lamp body; when the reflector cup and cup cover are rotated or pushed and pulled, the focal length of the LED to the reflector cup can be changed to achieve the purpose of arbitrarily adjusting the luminous angle and lighting. With the design of this case, after the light emitted by the LED is reflected, focused, and then refracted to the object, there will be no glare and glare problems when looking directly at the traditional LED.
