Abstract
The utility model provides an LED tube lamp structure. The LED tube lamp structure is composed of a light transmitting lampshade, lamp holders, a heat conduction insulating plastic plate, illuminants made of sapphire heat conduction light transmitting substrates, and a built-in driving power source. The light transmitting lampshade is in a straight tube shape, the illuminants are distributed on the heat conduction insulating plastic plate sequentially, connected through metal wires and connected with the built-in driving power source fixedly arranged on one side of the heat conduction insulating plastic plate, and the light transmitting lampshade is connected with the lamp holders. According to the LED tube lamp structure, the sapphire heat conduction light transmitting substrates have a good insulating property and a better thermal conductivity than traditional PCBs (printed circuit boards), heat generated by the illuminants can pass through the heat conduction insulating plastic plate in a heat conduction mode and is directly dissipated from the lampshade, so that the heat dissipation performance of the lamp is improved obviously; meanwhile, the LED tube lamp structure does not comprises a heat sink structure, so that light weight and manufacturing cost reduction can be achieved.
Description
(1) technical field
The invention belongs to the LED lighting technical field, be specifically related to the LED spot encapsulating structure that a kind of thermal diffusivity is good, light extraction efficiency is high.
(2) background technology
The different stages such as incandescent lamp, fluorescent lamp, electricity-saving lamp have been experienced in human illumination, have made significant headway at aspects such as improving light efficiency.Yet, for the consideration of falling cost, energy-saving and environmental protection aspect, also have the space that further promotes.And LED utilizes the solid-state semiconductor chip as luminescent material, have the luminous efficiency height, advantages such as volume is little, power consumption is low, long service life, environmental protection, its internal characteristics has determined that it is optimal conventional light source substitute, and its theoretical transformation efficient is higher 5 ~ 20 times than conventional light source light extraction efficiency.
The LED lamp is deep into illumination market with very fast speed at present, comprises street lamp, signal lamp, Landscape Lighting, room lighting etc.And the Design Mode of existing LED spot generally is that to take semicanal be that lampshade, semicanal are radiators, lamp pearl or chip are connected on the circuit board, circuit board is inserted in the groove at radiator semicircle pipe two ends, last again the two ends of radiator and lampshade is fixed on the lamp holder respectively.This sealing structure is bad, advances ash easily, shortens fluorescent tube service life.Have the problem that the back side can not bright dipping on the chip loading circuit plate, light extraction efficiency is lower.In addition, radiator is bigger with the aluminium amount in the structure, and cost is higher.
(3) summary of the invention
The LED spot structure that it is the printing opacity heat-conducting substrate with the sapphire that the purpose of this utility model is to provide a kind of, thermal diffusivity is good, light extraction efficiency is high.
The purpose of this utility model is achieved in that illuminator and built-in driving power that it is made by transparent lamp shade, lamp holder, moulded heat-conductive insulated plastics plate, with sapphire heat conduction light-passing board form, transparent lamp shade is straight tube-like, the inside pipe wall relative position is provided with the strip projection of an assembling folder moulded heat-conductive insulated plastics plate, illuminator is arranged on the moulded heat-conductive insulated plastics plate successively, connect illuminator by plain conductor, and be connected with built-in driving power on being fixed on moulded heat-conductive insulated plastics plate opposite side, transparent lamp shade is connected with lamp holder.
The utility model also has some technical characterictics like this:
1, described sapphire heat conduction light-passing board is the twin polishing sheet, the front is coated with metal electrode or prefabricated circuit, the back side is coated with the layer of metal reflective membrane, and chip is arranged on the sapphire heat conduction light-passing board with formal dress or upside-down mounting form, has the position of chip to be coated with fluorescent material except metal electrode.
2, described moulded heat-conductive insulated plastics plate two-sided is provided with prefabricated circuit, and illuminator is fixed on the moulded heat-conductive insulated plastics plate by bonding way.
3, described sapphire heat conduction light-passing board can be made according to light fixture and require to make different shapes such as square, rectangle, circle.
The beneficial effects of the utility model are: 1) adopt the integral type transparent lamp shade can avoid dust to enter, prolong light fixture service life; 2) adopt the coating single side sapphire wafer as multi-chip modules heat conduction light-passing board, the light that active layer sends not only can directly send from above, also can see through substrate and shine on the substrate back reflective membrane, upwards sends again, improves light extraction efficiency; 3) the own good insulating of sapphire heat conduction light-passing board, and thermal conductivity is better than the traditional PCB plate, and the heat that produces of illuminator can heat conducting form by the moulded heat-conductive insulated plastics plate, directly shed from lampshade, the heat dispersion of light fixture obviously improves; 4) do not adopt heat sink structure in the fitting structure, light fitting quality is light, and cost of manufacture reduces.

Fig. 2 is Fig. 1 side view.
(5) specific embodiment
Below in conjunction with Fig. 1-2 and the specific embodiment the utility model is further described.
